* Location: San Francisco
* Compensation: $100k +
An engineering consulting firm, is currently seeking a Bridge Surveyor for fabrication and construction of the new San Francisco Oakland Bay Bridge. The qualified candidate will be required to perform standard surveying practices and techniques in specific situations which may include but is not limited to the following duties:
• Perform the complex field and office surveying work, make precise survey measurements and interpret survey calculations.
• Research, analyze, check and adjust survey data; Research and compile evidence and documentation for boundary determination.
• Assist in planning, directing and coordinating the work of a group of survey personnel; Analyze situations accurately and take effective action
• Prepare clear, concise reports and correspondence; effectively document and communicate information for onsite Client Representatives
• Verify the accuracy of survey data including measurements and calculations for large structural steel bridge segments; Establish survey control points and multiple stations around fabricated steel segments during fabrication and pre-assembly yard operations
• Understand and be able to operate contractor’s T’3 Laser Tracker from Automated Precision, Inc. (API) to gather 3D data points from structure to import into Spatial Analyzer Software (SA) by New River Kinematics
• Be able to use a High Precision Total Station (Leica TCA2003) to import 3D data points into the SA Software
• Have an understanding of error sources inherent to survey methodology and apply proper modeling and propagation of the errors through to the final analysis such that determination of the overall accuracy of the survey can be made (instrument, environment and stochastic errors)
• Be able to maintain calibration checks and an understanding of the difference between the performance of the T3 Laser Tracker in IFM (interferometric) or ADM (Absolute Distance Measurement) modes
• Have an understanding in being able to facilitate a bundle adjustment process within the SA Software through their Unified Spatial Metrological Network (USMN) with the following steps:
1) Bundle adjustment of all instrument stations and their associated measurements through USMN.
2) Construction of best fit geometric shapes (points, lines and planes) to represent the components of the structure.
3) Query of the spatial relationships between the constructed elements to produce dimensions, angles and contours.
• Analyze USMN adjustments and establish a geometrical relationship with the actual design as a comparison check for surfaces, edges and points of interest on the structural segments
Requirements:
• Registration as a Professional Land Surveyor by the California Board for Professional Engineers and Land Surveyor is desirable
• 5 years experience with large construction projects (transportation preferred)
• Good interpersonal skills and capable of developing technical writing and communication skills
• PC applications/usage and CADD skills required
• Mathematics and procedures used in plane and geodetic surveying
• Fundamental surveying, mathematics and basic science as applied to surveying
• Methods of precise survey measuring and use/adjustment of precision surveying instruments (conventional and state of the art)
• Procedures, equipment and materials used in surveying, including conventional and state of the art
• Mapping and drafting techniques
• Knowledgeable in the California Coordinate System and the Code of Safe Surveying Practices
